Golden geckos will, without a doubt, no question about it, eat their own young.
In my experience it is easier to remove the adults to another enclosure prior to the eggs hatching, alternatively you can deli cup the eggs to make collecting the hatchlings easier.
If you try the deli cup method I believe you will be able to witness the adults trying to get at the hatchlings, this to me coupled with the loss of my first hatchlings was enough proof for me that I should not keep soon to hatch eggs and adults together.
